Im looking to get a PS3, and I would really like the MGS4 pack comming out this summer. Will the MGS4 80gb have the same backwards compatability as the earlier released (and now discontinued) 80gb in the motorstorm pack. I would really like the bc as I never owned a ps2. I still have a local retailer that has a motorstorm pack, so if theres no bc with the mgs4 pack, Id like to know so I can buy the bc 80gb before its sold.
